Hi i got a problem with Android JSON Parser in 2.3, all is ok in 4.0>. I look other topic they are talking about encoding (server) or other stuff server side, but i tried to put "test" in all my JSON field an the problem still persist. Here is my code : <pre><code>URL url = new URL(c.getString(R.string.url_ws) + url_ws); HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.setDoOutput(true); connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); connection.setRequestMethod("POST"); OutputStreamWriter request = new OutputStreamWriter(connection.getOutputStream()); request.write("&test=test"); request.flush(); request.close(); String line; InputStreamReader isr = new InputStreamReader(connection.getInputStream()); BufferedReader reader = new BufferedReader(isr); StringBuilder sb = new StringBuilder(); while ((line = reader.readLine()) != null){ sb.append(line + "\n"); } String json = sb.toString().trim(); try { JSONObject obj = new JSONObject(json); } catch (JSONException e) { e.printStackTrace(); Log.d(Tools.TAG+"/debug JSONException", e.toString()); return null; } </code></pre> Here is my exception <pre><code>debug JSONException(4184): org.json.JSONException: Value of type java.lang.String cannot be converted to JSONObject </code></pre> i saw double space between "Value" and "of" so i guess the problem is a empty string but i dont get it. thanks. EDIT it was a encode mistake in my JSON, <pre><code>char a = json.substring(0, 1).charAt(0); int ascii = (int)a; Tools.myLog(">"+ascii+"<"); </code></pre> i found 65279 char <h1>SOLUTION</h1> <a href="https://stackoverflow.com/questions/9691771/why-is-65279-appearing-in-my-html">Why is &#65279; appearing in my HTML?</a> encoding UTF-8 without BOM.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
